What is interesting about these objects is not that they appear to be the same craft, it's that they appear to be of terrestrial origin ( albeit very advanced ).
I substantiate this claim first by saying that i am an industrial design project manager and am constantly viewing radical concepts of all sorts of appliances and vehicles and if someone was to show me a concept drawing of this particular craft i would quite easily determine that there was A) a nose and cockpit section. B) wings of a fashion. C) an inverted tail section for stability.
I would not be suprised to see this craft wheeled onto the tarmac sometime in the next 20 years.
